Chlorine versus Bromine – What’s the Difference?

Chlorine and bromine are both common sanitizers used in hot tubs to kill bacteria and other microorganisms. The main difference between the two is the strength of the sanitizer.

Chlorine is generally considered to be a stronger sanitizer, and requires less of it to maintain proper levels in the water. Bromine, on the other hand, is a softer sanitizer, and requires more of it to maintain proper levels.

Additionally, Chlorine is more pH-sensitive than bromine, which means that the pH level of the water needs to be closely monitored and adjusted in order to maintain effective chlorine levels. Bromine is more stable in a wider range of pH levels.
